DSK format : DIRStruct FileEntry

[freemac]

Who knows more about floppy DIRStruct structure ?


Thing I know actually is :
-A DIREntry is on 4 first sector of dsk, A FileEntry does 32 bytes and matches with 16KB max.
-if first byte is xE5 (empty char that fill a virgin dsk) FileEntry is ignored.


What is between the red and the green bytes ?

CP/M information archive : disc formats

look at cpm2.2 directory structure.

EDIT: The number of sectors per directory, the start track of the directory and the number of files in the directory is all defined in the XDPB.

This doc has the XDPB for SYSTEM and DATA:

So my red byte is in fact "low byte" of counter (%32), and its "high byte" value (/32) is the byte just at left of my green byte 
Thanks a lot

The byte in the green box is a counter of 128 byte records. It can not be higher than &80, if it is &80 then look for a 2nd extent of the file (file is bigger than 16 KB). The byte after the file-name is the counter of the extent (0 for first extent, then 1, 2...).
